DMSO 1110 MIDTERM SOLVED 100% CORRECT.
CT Answer - An X-ray exam using multiple beams which produce a cross
sectional image.
MRI Answer - -Uses the property of protons aligning themselves in a magnetic
field and their reaction to radio frequency waves.
-The machine scans the body by turning small magnets on and off.
Nuclear Medicine/ Pet Scan Answer - Uses small amounts of radioactive
materials called radiotracers, a special camera and a computer to help evaluate
organ and tissue functions.
PACS Answer - -All diagnostic imaging is saved to PACS
-Picture archiving and communication system
-Saves images in Dicom format
-Allows interface with RIS (radiology information system) which populates the
patient information.
-Allows for query/retrieve function to compare exams.
prone position Answer - lying on abdomen, facing downward.
supine position Answer - lying on back, facing upward
, Ultrasound Answer - A mechanical wave. The Physical principals of the
transmission of high frequency mechanical sound waves.
Sonography Answer - Uses ultrasound to produce images.
Medical Use Answer - Typical medical use is 2 MHz to 20 MHz.
Benefits of Ultrasound Answer - -Does not use radiation
-Operator dependent
-Dynamic
-Portable
-Less expensive than other modalities
Sonographer Role/Duties Answer - *Check patient's chart to investigate prior
exams and notes
*Verify patient's DOB and Name
*Perform exam based on appropriate protocols
*Summarize findings using sonographic terminology to provide the radiologist
with an overview of the exam
*The Scope of Practice and Clinical Standards for the Diagnostic Sonographer
States "The sonographer integrates medical history, previous studies and
current symptoms in determining the appropriate diagnostic protocol"
*Sonographer salary between $70,000 and $74,00.
